How to Prepare Yourself for Green Lake Trek

Preparing for the Green Lake Trek requires both physical and mental preparation due to the trek’s challenging nature and high-altitude environment. Some guidance for you to prepare effectively will definitely help in your careful preparation.

1. Physical Preparation

Start Training Early

• Begin your training at least 4-6 weeks before the trek to build strength and endurance.
• Focus on cardiovascular fitness (running, cycling, swimming) to improve stamina.
• Incorporate strength training (leg exercises like squats, lunges, step-ups) to build the muscles needed for trekking.
• Include hill walks or stair climbing to get used to ascending and descending terrain.
• Endurance walks are necessary. Aim for at least 4-6 hours of walking with a loaded backpack to simulate trekking conditions.
• Altitude acclimatization is important. If possible, do some hiking at high altitudes (above 3,000 meters) to prepare your body for lower oxygen levels.

Mental Preparation

• Expect Tough Conditions:
  The trek takes you through remote, rugged terrain with altitude challenges. Be mentally prepared for long days, weather conditions and physical exertion.
• Positive Mindset:
  Keep a positive attitude, especially when dealing with physical fatigue, cold weather and difficult sections of the trek. Mental resilience will help you push through tough moments.
• Stay Motivated:
  Setting smaller milestones and focusing on one day at a time can make the trek more manageable.

Health and Medical Preparation

• Consult a Doctor:
  Visit your doctor for a check-up to ensure you are fit for trekking, especially at high altitudes. Discuss medications, vaccines and any health concerns.
• High Altitude Training:
  If you have no experience trekking at high altitudes, it is advisable to gradually ascend in the weeks leading up to the trek to prevent altitude sickness.
• Carry a First-Aid Kit:
  Include essentials such as painkillers, blister treatments, band-aids, anti-nausea tablets and any personal medications.
• Hydrate Well:
  Drinking plenty of water before the trek and staying hydrated during it is critical, as altitude and physical exertion can dehydrate you faster.

Gear and Equipment Preparation

• Trekking Boots: Invest in a sturdy, comfortable pair of trekking boots with good ankle support for uneven and rocky terrains. Make sure they are broken in before the trek to avoid blisters.
• Layered Clothing: At higher altitudes, temperatures can fluctuate, so wear moisture-wicking, breathable clothing. Bring warm layers, a waterproof jacket, gloves and a hat. A good down jacket for the evenings will be essential.
• Backpack: Use a well-fitted, comfortable backpack for your daypack and make sure it’s not too heavy. The weight should ideally not exceed 5-7 kg.
• Sleeping Bag: A high-quality sleeping bag rated for sub-zero temperatures is crucial for camping at Green Lake Base Camp.
• Water Purification System: Carry a water filter or purification tablets, as fresh water sources are available during the trek but might need purification.

Learn about Altitude Sickness

• Symptoms: Headaches, dizziness, nausea and shortness of breath are common at high altitudes.
• Prevention: Gradually acclimatize by spending a day or two at intermediate altitudes. Take it slow, avoid exertion, and rest often. Drink plenty of fluids, avoid alcohol and eat high-carb foods.
• Treatment: If symptoms appear, descend to a lower altitude and rest. Diamox is commonly used to prevent and treat mild altitude sickness (consult your doctor before using).

Prepare for Remote Trekking Conditions

• Limited Connectivity: Be prepared for limited or no mobile phone signal, so it is important to leave your travel itinerary with someone and ensure you are in touch with local authorities or a guide.
• Respect Nature: Bring eco-friendly products, pack out all trash, and follow responsible trekking practices.

Mental Preparation for Remote Environment

• Isolated Trek: The Green Lake Trek takes you deep into the mountains, far from civilization. Be mentally prepared for long, solitary stretches where the surroundings are untouched by modern life.
• Cultural Understanding: Respect the local culture and customs, especially the Tibetan and Sikkimese traditions.

Proper Nutrition

• High-energy Foods: Stock up on energy-dense snacks like nuts, energy bars, dried fruits and chocolate. For meals, consider lightweight, freeze-dried meals or foods that require minimal cooking.
• Pre-Trek Nutrition: Start eating a balanced diet rich in carbohydrates, proteins and healthy fats in the weeks before your trek to fuel your body adequately.

Test Your Gear

• Trial Trek: Do at least one or two trial treks with your gear, especially the backpack and boots. This will help you make necessary adjustments and avoid issues during the trek.

Book a Guide or Group Tour

While the Green Lake Trek can be done independently with permits, it is recommended to go with a licensed guide for safety, navigation and acclimatization management. Group tours often have experienced guides and support, which enhances the overall trekking experience.
